Rockshore Wet Boots (Water Drain Pin Felt [FS-080U] 28.0cm I purchased these new from a Mercari shop last week and they are rockshore shoes with felt spikes, used for about half a day. I bought a size larger assuming I would wear waterproof socks or wet gaiters, but they were too big even with both included insoles. For reference, my actual foot size is 26cm. I wear 27.5cm in New Balance, Adidas, and Converse All Stars, and either 27cm or 27.5cm in Nike depending on the shoe. Shimano's Geolock game shoes fit me perfectly in 27.5cm after trying them on. After using them, I rinsed them thoroughly in lukewarm water to remove salt and washed them with diluted neutral detergent. When I lightly brushed them, the surface of the adhesive at the border between the rubber and neoprene became rough and whitish, so I touched it up with Some Q. However, I don't think there will be any particular problems with use.
